OIL-BURNER,

Application filed December 29, 1919.

y To all whom it may concern i Waterloo,

that I, EDWIN DARBY, a United States, residing at in the county ofBlackhawk and State of Iowa, have invented certain new and usefulImprovements in Oil-Burners, of which the followingY is a specification.

This invention relates to a liquid fuel vaporizer andheater designed foruse in connection with stoves, of both heating and cooking type, farmtank heaters and other forms of stove or furnace structure.

As the invention relates to the construction of the burner, vaporizingcoil, and connected parts, I have not shown or described the stove ortank heater, as the construction of these would depend on the make ofstove or tank heater employed, and is outside of the present invention.

The invention consists in the novel features of construction hereinafterdescribed, pointed out in the claims and shown in the accompanyingdrawings, in which Figure l is a plan view partly in section.

Fig. 2 is a section on the line.r 2`2 of Fig. l.

In the drawing l is a suitable base having the form of a shallow trayand providing a drip pan 2. The base is centrally cut out as at 3, thiscut out portion being inclosed'by a vertical wall Il., spaced from theedge of Be it known citizen of the l the opening 3, and which forms theinner are preferably three in number.

wall of the drip pan 2. Radial ribs 5 eX- tend transversely across thedrip pan and These ribs are higher than the side walls of the pan and attheir inner ends are cut out to form shoulders 6, said shoulders beingin the horizontalV plane of the drip pan walls, including the` innerwall 4. A dome or cap 7, downwardly is supported on the 6. Restingopening 3 is a double walled burner 8, the inner wall being perforatedas at 8S, the air space between the walls being closed at the bottom andopen at the top. The burner extends upwardly into the dome 7 openingshoulders and affords communication through theV opening 3 with thedome. As the dome is elevated by the shoulders 6 it also communi` cateswith the drip pan 2.

An oil feedV pipe 9 leads from any suitable source of supply and is bentin the formV of coils 9a about the dome 7, the coils resting on the ribs5, and theppipe Yis then bent Specification of Letters Patent.

downwardly and upwardly into alinement with the opening 3 terminating ina discharge orifice 9b. Where it passes through the drip pan it isinclosed by a boss l0. A supplemental feed pipe l1 depends over the drippan 2 and supplies said pan with oil for ignition purposes, the panbeing supplied with the usual asbestos wick, or with any suitable oilabsorbing material.

A depending flange 12 forms a support for the supply pipe at a pointbelow the burner. l

A heat retaining the coils 9a.

Suitable valves, not shown, are employed in the pipes 9 and l1, and arelocated at any convenient point, and a supply reservoir, not shown, maybe located where most convenient, or as considerations of safety maydictate.

The oil vaporized in the coils will be discharged through the orice 9binto the burner 8 which also serves as a mixer and the flames willspread through the dome and plate 13 is placed over out from under itslower edge.

What I claim is V:-

l. An oil burner comprising a base forming' a drip pan, and having acentral opening, radial ribs extending across said pan, the pan havingouter and inner walls, a

downwardly open dome resting on said ribs, a burner mounted on the basein alinement with the opening and extending upwardly into said dome, anda supply pipe, a portion of said pipe being coiled about the dome andresting on said ribs, as and for the purpose set forth.

2. An oil burner comprising a base forming a drip pan with inner andouter walls, the central portion of the base within the burner mountedon the marginal portions of said cut out portion of the base, andretained in position by the inner drip pan wall, transverse ribsextending from wall to wall of the pan and having shoulders formed ontheir inner end a dome mounted on said shoulders, means for supplyingoil to the drip adapted to discharge an oil vapor into said burnerthrough the cut out portion of the base, a portion of said pipe beingcoiled about the dome and supported by said ribs.

3. In an oil burner, a drip pan, a dome supported above said pan, saidpan having Patented ov. 30, 1920. I
